New book on Schematron

Erik Siegel's Schematron: A Language for Validating XML is out now from XML
Press, as paperback (260 pages, nicely set on good wide pages, lays flat
fairly well), eBook, .mobi (Kindle) and PDF. It features the Schematroll on
the cover.

It fills in a big gap, and congratulations to Erik for a well written and
thorough work. It goes through each element and attribute, and has a primer
in XPath.

(Of course, if you want to pay 8 times more for a book 8 times smaller, you
can get the ISO Standard!)

I have a little review at Schematron.com.

Cheers,
Rick
